How is the Aspire 4 different from other 64Audio universal and custom IEMs?

The new 64Audio Aspire 4 IEM is unlike any other 64Audio IEM before it, with the most notable difference being aesthetics and build.

The Aspire 4 uses durable ABS shells and stainless steel nozzle alongside a new IPX cable, whereas 64Audio universal IEMs use a two-piece metal shell with removable Apex Modules and a standard 2-pin connector.

Compared to 64Audio custom IEMs, the Aspire 4 features a different shell materials (ABS vs acrylic) and connectors (IPX vs 2-pin). The Aspire 4 are universal fit and feature a generic shell shape, while 64Audio CIEMs are custom-molded to a user's specific ear shape.

Another notable difference is in the Aspire 4's driver configuration. The Aspire 4 uses a hybrid driver setup, whereas universal and custom 64Audio IEMs primarily come with Balanced Armature drivers. 64Audio hybrids like the Duo, Volür, and Nio are closer to the Aspire 4 in terms of driver setups since these IEMs combine dynamic drivers with Balanced Armatures to deliver their sound.
